|---|---|---|
| \(m^7\) | B1 | cao |
| Answer | Mark | Mark scheme |
|---|---|---|
| \(125n^3p^9\) | B2 | cao |
| (B1 | for 2 of 3 terms correct in a single product) |
Additional guidance
Allow multiplication signs
\(125n^3p^x\) or \(125n^xp^9\) where \(x \neq 0\) or \(an^3p^9\) where \(a\) is a number

|---|---|---|
| \(8q^6r^3\) | B2 | cao |
| (B1 | for 2 of 3 terms correct in a single product) |
Additional guidance
Allow multiplication signs
\(8q^6r^x\) or \(8q^xr^3\) where \(x \neq 0\) or \(aq^6r^3\) where \(a\) is a number
